 Topic: Kinda reached a milestone,,,,,
Posted: 06 Sep 2020 at 8:24pm |
Well,,,I got the Brutus 468 all lashed up, painted and shoehorned into the 1982 Silverado a couple of days ago,,,!!!!  Got all the muffler work and tail pipes all welded up and started on lashing up all the underhood hoses ect,,ect, Finally got to where I could not stand it no more so I hot wired a hot to the new distributor thru a toggle switch and Fired that Mother up,,,,!!! WHEW,,but do it sound good,,!! A whole lots better than the tired 305 that it replaced,,,, Here's my questions,,,,(ya'll knew they was comin, din'cha?) Anyways,,the guy I bought the trk from was a kinda of a curtain climber and he fancied himself an expert on electric horns and lights and he cut and spliced into and out of various parts of the under hood wiring harness to the point where it one big friggin mess,,!! I have removed four (4) different horns and left the two factory horns. PLUS he had added several extra speakers , a stereo and a 6 CD changer,,,dang!! The trk has the dual fuel tanks and I had to replace the broken switch on dash,,but the fuel is still not getting to the carb. I have a temp setup with a hose and funnel and feeding the carb as it runs,,,,Does anybody know IF GM used TWO switching valves on this type system,,,?? ,,,OR,,?

Hey Steve,,,"You're the best,!!" that is exactly what I was lookin for,,, I'ma gonna crawl under the trk first thing and pull the "Pollack valve" to see why it ain't switching. I had put 3 gallons of fuel in the left side tank and the right side tank is prolly empty since the trk has been settin so long. I seem to remember on the first squarebody I had was a 1980, I think, and a guy told me to reroute the fuel lines to the left side of trk and install a 3 way manual valve mounted just under the driver's seat that you could reach down and switch tanks from driver's seat,,,,but do not remember how we addressed the return lines,,,or,,,if there WERE any return lines,,,,,?? HMMMmmmm,,,I wonder if you could just plug the return line at the fuel pump,,and at both tanks,,,,???

I'm just curious bout something,,on them return fuel lines,,,,,On this trk,,,it originally had the return fuel line and must of had the matching fuel pump. When I bought the trk, it had a new fuel pump "Without" the return line connection built on the fuel pump. I did save the pump but it would not fit on the big block, so I re-used the pump that came with the big block and it does have the extra connection for the return line,,so I hooked it up,,,,,? I've been reading bout lots of people havin problems with those switching valves and I now remember one of my company pickups having to get that valve changed out a couple of times. I figure that this BBC with the Edelbrock Preformer carb is gonna like that gasoline pretty much and there ain't ever gonna be ANY fuel goin back to the tank,,,,SOOooo,,,I'm for plugging the return line at both ends, remove the switching valve,,,and let the new owner of the trk try to figure it all out"IF" he wants both tanks to operate,,,,Ten Four,,,???

 Joe let tell you a story. The old man had 75 gallon tank in the back of his 75 Chey so you could hall cows all day and not stop and gas up. At well over 200,000 mile he orders up a new truck. Will not think of getting the 2 tank option,as he had a big tank to put in the bed. Well he get the hitch and tank put in that 82 GMC. You run off that big tank and the gas gauge goes up to full.  He was so happy new truck was making gas. Well that gas making truck started sputtering and would die.  He bugged the outfit that sold this truck they had not a clue. A fair number of them good old Joe can fix it guys got bugged too.
After much frustration and many mechanics getting a talking to. You NEED A RETURN LINE AND A TANK THAT IS NO OVER FULL. If you don't it floods the charcoal vapor canister (all that fun air pollution stuff) and they don't run when flooded. You let the bugger sit a few hours it will run for a bit till it floods again.
Now if this clever O'l Joe has stripped the all the extra "keep the air clean" crap off who knows what you can do.
This one got "fixed" by running the by pass line to the big tank.
All was good till he wanted to run the original tank for some reason and the gas had gone bad.
*** But that did lead to me finding the best weed killer EVER. Living in the Land of Fruits and Nuts you need to be careful how you dispose of toxic wast. So I put some of that old bad gas in the pump up hand sprayer. Spray some tough weeds that grow all summer here in that 110 and not had a rain in 3 month. By the time I got done spraying that 2 gl of bad gas and walked back to where I started (I walked a lot faster 25 years ago) those O'l nasty weeds was wilted and turning brown.

Some Quadra jets returned to the tank. The Edelbrock will not. Plug at the tanks. Use switch for gauges only and get a manual selector valve as you mentioned. Make sure gas cap vents and smoke them thar tars.

OK,,now I'm needing some more info for finishing up ole Brutus 454 in the Silverado. None of the accessory brackets from the 305 are fitting on the 454,,Why didn't I already know that? I did manage to "retrofit" (I like thet word) the throttle bracket to work on the Edelbrock and added the kickdown bracket to it and works Many Wonderfuls,,,,, BUT,,,the alternator, power steering and A/C brackets are a total "Aw Chit",,,,, I checked out a bunch of "images" on the net but cannot find anything that shows the brackets theirselves,,,,. Some outfits sell the Custom Chrome brackets but they place the alternator and A/C way high up on the engine and no way I'm spending that kind of dollars for that chit,,,,,,,Maybe them two professional "INTERNET LOOKERS" like ole JC and Chask can find em but I ain't havin no luck,,,,OR,,
Does anybody have an early to mid 80's chevy trk or car with the BBC that might could take some pics so I gots an idea what the brackets look like,,,??? I done been to 3 wrecking yards and no luck,,,,,

Different fuel pump on air conditioned and non - so some had return lines and others did not - without the switch operated the gas gauge and energized the solonoid for other tank but default was to left tank (I think) only. Latter used a solonoid that had multi ports to route the return hose and stayed in position with no default . Acted like more or a linear actuator motor to keep whatever position the switch was in

Well,,Coke,,,I DID have lots of plans for this trk as it is really nice and now with the big Bruiser BBC, It ought to sell right quick. It has been a "Learnin project" what with puttin the big block in the place of the 305,,for sure. I have made myself a firm promise that I am no longer doing any more guvment Jobs for anybody as I do want to get back to my favorite,,,55 Chevy. I ain't gettin no younger any more and that has to be my next project after this Black trk. I been waitin on a dang wiring diagram for over 3 weeks now as the Curtain Climber PO did a number on the original wiring harness,,,,he had a sweet spot for horns and lights, he did,,,,, I was able to fashion a new bracket for the throttle cable and the kickdown cable and looks almost factory. I finally hollard "calf Rope" on the brackets for the power steering and alternator and ordered new ones,,they be here next Wed so I can start doing the final detail on the trk and slap a "For Sale" sign on it,,,,,,,,I'ma let the new owner worry bout mounting the A/C,,if he wants to,,,,,, I'm thinkin he gonna be too busy tryin to fry them Ta'ars tho,,,,,,,
